This patch modifies epoll, kqueue and evports (the 3 pollers that support busy polling) to only update the local date in the inner polling loop, the global one being done when leaving the loop. Testing with epoll on a 24c/48t machine showed a boost from 53M to 352M loops/s, indicating that the loop was spending 85% of its time updating the global date or causing side effects (which was confirmed with perf top showing 67% in clock_update_global_date() alone).
